Two, work principle:

，當(dāng)浮子所受上升力大于浸在流體中浮子重量

，浮子便上升

，環(huán)隙面積就隨之增大，環(huán)隙處流體流速立即下降

，浮子上下端差壓降低

，作用于浮子的上升力亦隨著減少，直到上升力等于浸在流體中浮子重量時

，浮子便穩(wěn)定在某一高度

。">ZW-LZ series clamp type metal tube rotameter is the medium to be measured through a conical measuring tube float from upper and lower ends of the differential pressure generated form the upward force, when the float was immersed in a fluid on the lift is greater than the weight of the float, the float will rise, annulus area increases, the annulus fluid velocity decreased immediately float on the lower end of the differential pressure is reduced, to float upward force also decreases with, until the lift is equal to the weight of the float when immersed in a fluid, the float will stabilize at a certain height. The float position that corresponds to the size of the measured medium flow. ，在浮子隨介質(zhì)上下移動時

，磁場隨浮子的移動而變化。">A built-in magnet, the float with the medium moves up and down, with the movement of the float magnetic field changes.
